Answer:
The total energy of the photons detected in one hour is 7.04*10⁻¹¹ J
Explanation:
The energy carried by electromagnetic radiation is displaced by waves. This energy is not continuous, but is transmitted grouped into small "quanta" of energy called photons. The energy (E) carried by electromagnetic radiation can be measured in Joules (J). Frequency (ν or f) is the number of times a wave oscillates in one second and is measured in cycles / second or hertz (Hz). The frequency is directly proportional to the energy carried by a radiation, according to the equation: E = h.f, (where h is the Planck constant = 6.63 · 10⁻³⁴ J / s).
Wavelength is the minimum distance between two successive points on the wave that are in the same state of vibration. it is expressed in units of length (m). In light and other electromagnetic waves that propagate at the speed of light (c), the frequency would be equal to the speed of light (≈ 3 × 10⁸ m / s) between the wavelength :
![f=\frac{speed of light}{wavelength}](https://tex.z-dn.net/?f=f%3D%5Cfrac%7Bspeed%20of%20light%7D%7Bwavelength%7D)
So:
![E=\frac{h*speed of light}{wavelength}](https://tex.z-dn.net/?f=E%3D%5Cfrac%7Bh%2Aspeed%20of%20light%7D%7Bwavelength%7D)
In this case, the wavelength is 3.35mm=3.35*10⁻³m and the energy per photon is:
![E=\frac{6.63*10^{-34}*3*10^{8}}{3.35*10^{-3} }](https://tex.z-dn.net/?f=E%3D%5Cfrac%7B6.63%2A10%5E%7B-34%7D%2A3%2A10%5E%7B8%7D%7D%7B3.35%2A10%5E%7B-3%7D%20%7D)
E=5.93*10⁻²³ ![\frac{J}{proton}](https://tex.z-dn.net/?f=%5Cfrac%7BJ%7D%7Bproton%7D)
The detector is capturing 3.3*10⁸ photons per second. So, in 1 hour:
![E=5.93*10^{-23} \frac{J}{proton} *3.3*10^{8} \frac{proton}{s} *\frac{60}{1} \frac{s}{minute} *\frac{60}{1} \frac{minute}{hr}](https://tex.z-dn.net/?f=E%3D5.93%2A10%5E%7B-23%7D%20%5Cfrac%7BJ%7D%7Bproton%7D%20%2A3.3%2A10%5E%7B8%7D%20%5Cfrac%7Bproton%7D%7Bs%7D%20%2A%5Cfrac%7B60%7D%7B1%7D%20%5Cfrac%7Bs%7D%7Bminute%7D%20%2A%5Cfrac%7B60%7D%7B1%7D%20%5Cfrac%7Bminute%7D%7Bhr%7D)
E=7.04*10⁻¹¹ ![\frac{J}{hr}](https://tex.z-dn.net/?f=%5Cfrac%7BJ%7D%7Bhr%7D)
The total energy of the photons detected in one hour is 7.04*10⁻¹¹ J
<span>The type of bond that a
Phosphorous pentachloride have is an Ionic Bonding. It is a form of chemical
bond that encompasses the electrostatic attraction between oppositely charged
ions which serves as the primary interaction happening in ionic compound. Phosphorus
has 5 valence electrons and Chlorine has 7 valence electrons. Phosphorus contributes
1 electron to each chlorine and all the 6 achieve 8 electrons in the outer
shell thus creating an ionic bond.</span>

Answer:
Explanation:
Part two of Dalton's theory had to be modified after mass spectrometry experiments demonstrated that atoms of the same element can have different masses because the number of neutrons can vary for different isotopes of the same element. ... Scientists have even developed the technology to see the world on an atomic level!
hoped i helped you :)
I believe the answer is true. Hope this helps.
